Swedish name: Påfågelciklid
Scientific name: Astronotus ocellatus
English name: Oscar
Astronotus ocellatus is a species of fish from the cichlid family known under a variety of common names including oscar, tiger oscar, velvet cichlid or marble cichlid. In South America, where the species naturally resides, A. ocellatus are often found for sale as a food fish in the local markets. However, its slow growth limits its potential for aquaculture. The species is also a popular aquarium fish.
Appearance, size and coloration A. ocellatus have been reported to grow to a length of 45 cm (approximately 18 in) and a mass of 1.6 kg (3.5 lb).[1] The wild cught forms of the species are typically darkly coloured with orange ringed-spots or ocelli on the caudal peduncle and on the dorsal fin. It has been suggested that these ocelli function to limit fin-nipping by piranha
(Serrasalmus spp.) which co-occur with A. ocellatus in its natural environment.
The species is also able to rapidly alter its colouration, a trait which facilitates
ritualised territorial and combat behaviours amongst conspecifics. Juvenile A. ocellatus have a different colouration to adults and are striped with white and
orange wavy bands and have spotted heads.
